Any comments on this 16x16 matrix switch (HDMI) ?

So ...

I have a bunch of HDMI *outputs* like UltraHDMI and n64Digital N64s and three different OSSC and 3-4 raspberry pis and ...

I also have a bunch of HDMI screens of various sizes and placements ...

So it seems like the smart thing to do is wire everything up into a HDMI matrix switch and manage sending/receiving the video with simple button pushes. This 16x16 HDMI switch seems relatively inexpensive and very full-featured:

Any issues or gotchas I should be aware of when looking for a matrix switch like this ?

Specifically:

- lots of my video sources are not really HDMI - like a RGB modded SNES output to an OSSC to turn it into HDMI

- lots of my monitors are also not HDMI - they are 4:3 DVI monitors (yes, I am buying an EDID injector)

Can I assume that if the OSSC can talk to the DVI monitor on their own, they can also talk like that through the matrix switch ?


EDIT: Yes, now I have seen the two very good posts already here on the forum - so the big questions I have seem to be answered and I can go from there ... mostly wondering now if anyone has seen or heard of this wolfpack device/brand ...

No, you can't assume that. OSSC compatibility was the main focus of Dirk's testing, and compatibility was poor.

A frequent issue was dropped frames (sometimes with the OSSC, sometimes with something like a PS4 Pro), or signal dropouts, or EDID issues... See his test results to see the sort of typical issues he had.

I would be especially worried about that Wolfpack switch since it also includes integrated scaling for every output port. It's processing the signal far more deeply than a normal switch.

Thank you. Very glad I asked and I will re-read those threads and see what I can come away with ...

The issue is, I really want a 1U device - I don't want to eat up my entire rack with a 4U device, etc.

strange that you have multiple OSSCs when instead you should unify output for all devices and use an auto switcher, like any by superg.

From the product literature:

"1080p Down Scaler on Each Output"

and:

"Each HDMI output of this 16x16 HDMI Matrix supports 4K2K to 1080P downscaler independently. "

The negative effects of this would be video weirdness or flickering or dropped frames, correct ?

Should I investigate whether that scaling can be disabled or would you assume it is enabled always ?

EDIT:

OK, from the user manual the settings are:

Set hdmi output y port output
scaler mode，y=0~16 (0=all),
z=1~3(1=bypass, 2=4k->1080p,
3=Auto)

... so it looks like you can set the scaler to "bypass" which I assume means, no scaling ? Not sure what this matrix switch would do with a 4:3 signal sent to a 4:3 monitor, however ...
